[0002]

2. Description of the Related Art As a method of removing odors in toilets and refrigerators, a method of masking a bad odor with a conventional fragrance and a method of adsorbing odorous components with activated carbon A deodorant composed of L-ascorbic acid and ferrous sulfate (trade name) Anico, Shokoku Sho 61
No. 43091) is known.

[0003]

However, the above three methods have the following problems. That is, the method (1) is not a method of removing odorous substances, but merely a method of coating a bad odor with an aromatic substance to impart aromaticity, and different people have different tastes for odors. Since the method (1) has a limited adsorption capacity and is relatively expensive, it has a limited spread. The method of (1) was devised to improve the disadvantages of (1) and (2), but L-ascorbic acid, which is one of the constituent materials, is expensive and is not always widely used.

The present invention solves these problems and provides an inexpensive and easy-to-use deodorant.

[0005]

Means for Solving the Problems The present inventor has developed various ideas with the intention of developing the above concept and developing a product that is easily disseminated using inexpensive raw materials. A mixed aqueous solution of a ferrous salt and a cupric salt is impregnated with a ferrous salt aqueous solution by impregnating a crushed product of normally-disused dead plants such as rice straw, wheat straw, stalks of syrup, and bamboo leaves. It was discovered that the odor adsorbing ability of the dead plant pulverized product was significantly increased.

Therefore, the present invention comprises a deodorizing agent characterized by comprising impregnating a crushed product of a dead plant with a ferrous salt aqueous solution alone or a mixed aqueous solution of a ferrous salt and a cupric salt. The present invention relates to a deodorizing structure in which such a deodorizing agent is accommodated in a bag-shaped non-woven fabric or Japanese paper, and a sand for pet animal excrement treatment in which the deodorizing agent and granular bentonite are mixed to form a sand.

The present inventor has found that the cellular tissue of a plant has extremely fine voids, and that the molecular structure of lignin, which is a part of its constituents, is a structure that L-ascorbic acid is prone to redox. Focusing on the fact that they have a large number of similar molecular structures, it is presumed that if they are utilized, they will exhibit a higher deodorizing function than L-ascorbic acid, and as a result of various studies, they have reached the present invention. It is a thing.

A crushed product obtained by crushing dead plants such as rice, wheat, sycamore, bamboo, and bamboo leaves by a crusher, for example, a Wiley-type crusher (a size that can pass through a mesh of 2 mm of a sieve is preferable). However, the size of the pulverized particles is not particularly limited) and the ferrous salt aqueous solution is uniformly mixed and impregnated. As the ferrous salt, any of ferrous sulfate, ferrous chloride, ferrous nitrate, etc. may be used, or a mixture thereof may be used. The amount of the ferrous salt added to the dead plant does not need to be particularly limited, but should not be unnecessarily increased. For example, in the case of ferrous sulfate heptahydrate, 10% to 30% based on the dry plant. Excellent deodorizing performance is exhibited at a concentration of%. The aqueous solution concentration of the ferrous iron salt to be sprayed is not particularly limited, but is 5 to 25
% Aqueous solution is preferably sprayed and impregnated uniformly. In this case, if a mixer such as a ribbon blender is used to spray and mix, the mixture is uniformly mixed and impregnated.

After mixing the ferrous salt, the water content is dried. The drying method may be reduced pressure drying or normal heat drying, but a lower drying temperature is preferable, and drying at 90 ° C. or lower is desirable. The degree of drying is not particularly limited, but the water content may be such that the pulverized product can be easily handled.

When a cupric salt such as copper sulfate, copper nitrate, cupric chloride alone or a mixture thereof is added to the ferrous salt, the adsorption performance may be improved as compared with the case of the ferrous salt alone. confirmed. The addition amount of the copper salt is not particularly limited, but 5 to 20% is sufficient with respect to the ferrous salt.

It has been confirmed that the crushed plant crushed product thus obtained is impregnated with a ferrous iron salt or a mixed impregnated product with a cupric salt has superior deodorizing performance to conventional deodorizing agents. Was done.

The embodiments of the present invention will be specifically illustrated below, but the present invention is not limited thereto.

[Example 1] Large sawdust generated in a sawmill was air-dried for 2 m.
40g which passed through the m sieve, 5g of ferrous sulfate heptahydrate
Is uniformly spray-impregnated with an aqueous solution of 150 ml of water dissolved in water, and naturally dried at room temperature. This impregnated product is designated as the deodorant 1 of the present invention.

Similarly, an impregnated product produced in the same manner except that 5 g of ferrous sulfate heptahydrate was changed to 10 g was designated as the deodorant 2 of the present invention.

1 g of each of these deodorants is sampled, placed in a glass bottle having an internal volume of 240 ml, and a 10% aqueous ammonia solution is dripped with a mini pipette and sealed. The number of drops is 2
Prepare 4 drops, 6 drops, and 6 drops.

Similarly, 40% methylamine aqueous solution 2
Drops, 4 drops, 6 drops are added to each impregnation and sealed.

After left at room temperature for 1 hour, the concentrations of ammonia and methylamine in the bottle were measured using a gas detector tube manufactured by Gastec Co., Ltd. As a blank test, the case of using the sawdust alone was also evaluated.

The results are shown in Table 1.

From the above results, the deodorizing agent 1 of the present invention impregnated with a ferrous salt, although the adsorbing performance is not so great with the large sawdust alone.
It was revealed that in Nos. 2 and 3, the adsorption performance was remarkably enhanced, and the adsorption performance was further enhanced as the impregnated amount of the iron salt was increased.

[0020]

[Example 2] Using the sample of the deodorant 2 of the present invention of Example 1, the adsorption performance was compared with the commercially available coconut shell activated carbon "Kimco" and the deodorant "Anico". The test procedure was exactly the same as in Example 1, and the ammonia aqueous solution and the methylamine aqueous solution were 10 drops and 8 drops, respectively.

Table 2 shows the measurement results.

[Example 3] Rice straw is cut into pieces each having a length of 3 mm and crushed with a coffee mill. To 25 g of this pulverized product, 40 ml of a 7% aqueous solution of ferrous sulfate heptahydrate is uniformly sprayed by spraying and dried at room temperature. This ferrous sulfate-impregnated rice straw is used as the deodorant 3 of the present invention. 1 g of this is sampled, placed in a glass bottle having an internal volume of 240 ml, 10 drops of 10% aqueous ammonia solution are dropped by a mini pipette, and immediately sealed. Similarly, commercially available palm shell activated carbon Kimco and the deodorant Anico were tested as comparative examples. Ammonia concentration in the glass bottle was measured with a gas detector tube after 1 hour from the dropwise addition of ammonia.

Similarly, the case where 8 drops of a 40% methylamine aqueous solution were dropped was evaluated.

The results are shown in Table 3.

[0025]

Example 4 To 10 g of the sawdust used in Example 1, 150 g of ferrous sulfate heptahydrate 10 g and copper sulfate pentahydrate 2 g were added.
Spray the mixed aqueous solution dissolved in
Air dry. This impregnated product is designated as the deodorant 4 of the present invention.

Similarly, 10 g of the ground rice straw product used in Example 3 is impregnated with 150 ml of the above mixed aqueous solution and air dried. This is designated as Deodorant 5 of the present invention.

1 g of these samples was sampled in a glass bottle, 12 drops of 10% aqueous ammonia solution and 8 drops of 40% methylamine aqueous solution were dropped in the same manner as in Example 1, and the mixture was allowed to stand at room temperature for 1 hour and then the gas concentration in the bottle was changed to gas. Measure with a detector tube. For comparison, Anico and Kimco were also evaluated.

The results are shown in Table 4.

From the above results, it was revealed that the adsorption performance is remarkably improved by the synergistic effect when the divalent copper ions coexist rather than the monovalent iron ions alone.
